Introduced last year, the new A3 range adds a convertible for 2015, and the five-door Sportback returns as an advanced hybrid later in the year. The sedan offers no less than 4 four-cylinder engines: 1.8L turbo (170 horsepower), 2.0L turbo (220 horsepower), 2.0L turbo S3 (290 horsepower) and the frugal 2.0L TDI turbodiesel (150 horsepower). All engines share a six-speed dual-clutch automated manual, with standard front-wheel drive and optional quattro all-wheel drive.
